Electron Energy Gain in laser ion channel affected by the space-charge potential and helical wiggler and external uniform magnetic fields

In this paper, the electron energy gain and its relativistic dynamics in an ion-channel formed due to the laser pulse and under influence of the channel space-charge field and heliacal wiggler as well as the external magnetic field have been investigated. The equations for investigation of the electron dynamics are the tree-dimension Lorentz equations. For analytical analysis of the obtained equations, a three-dimension single particle code is used as well. The electron energy gain and the relativistic electron dynamics drastically are affected by the ion-channel potential and the helical wiggler and external uniform magnetic fields. The results of this paper can be significant in the selection of the appropriate parameters for plasma-based accelerators design.
